- Studies :
Better knowledge about how a temporary pond functions leads to better
a better understanding of how to manage and protect it. For this reason,
scientific analyses, inventories of species and ecological monitoring
are carried out regularly in the Roque-Haute Reserve.
Scientific studies in progress
Inventories in progress
Professional management tools
Held in high scientific regard for many years, the
Reserve was, in 1990, invested with a Scientific
Committee to provide technical aid and
expertise to the Management Association.
The renown of Roque-Haute in scientific circles
is demonstrated by the fact that people from the latter account for nearly
20% of all visitors.
Scientific studies in progress
:
1- Study on the filling-up of the temporary ponds
2- Study on the dynamic of Marsilea strigosa populations
3- Study on trends in the grouping of Isoetes colonies in the ponds
4- Evaluation of the impact of boar on the ponds
5- Study of factors affecting Cape Groundsel colonies and their impact
on protected pteridophytes
6- Analysis of the hydrological functioning of the ponds
7- Experiments on the effect of restoring habitats on the development
of vegetation in the ponds
8- Experiments on the effects of reducing maritime scirpus populations
on the development of plants, primarily isoetes, in the ponds
9- Characteristics of ponds, with reference to hydracarian populations
10- Publication of lists of species (aquatic invertebrates) new to science,
found on the Roque-Haute Reserve
Inventories in progress :
1- Lepidoptera (butterflies)
2- Birds
3- Bryophytes (mosses and liverworts)
4- Hydracarians
Professional management tools :
- the Geographic
Information System helps scientists and managers
to understand the evolution of a natural habitat more easily. It enables
exact maps to be drawn of vegetation, natural habitats, hydrology, the
infrastructure, paths, etc
Certain phenomena (such as the invasion
of pond banks by ligneous plants) can be understood better by superimposing
the 1962 map onto the 1996 one, and decision-making is facilitated (to
give just one example, knowing where a path should be constructed so that
it avoids the reproductive sites of the newt!).
- the Roque-Haute
Meteorological station
enables the rainfall (i.e. the only water that the ponds receive), the
temperature, the light intensity, the hygrometry and the wind speed to
be measured - vital data for the understanding of water loss by evaporation
- throughout the seasons. The station is powered by solar energy and average
daily values are recorded electronically on a special cassette. The data
recorded thereon is gathered up by the team once every three months and
transferred to the main computer.
